Email List Validator

Email List Validator cleans pasted email lists by separating valid addresses from invalid entries and removing duplicates. It is useful for QA lists, test accounts, newsletter import checks, CRM cleanup, support macros, and spreadsheet handoffs where one bad address can break an import.

The validator accepts newline, comma, or semicolon separated input. It reports counts, outputs a clean deduped list, and keeps invalid entries visible so you can fix typos instead of silently losing data.

This is a syntax and cleanup tool, not an email deliverability service. It does not verify inbox existence, send network requests, or contact mail servers, which keeps the workflow fast and local.
